This piece is high up on a retaining wall. The chair is by Brian Goggins and is very similar to his Defenestration Piece running South of Market.
The description that accompanies the piece is “Fortitude” A submarine chair transforms our perception of space and objects. This “submarine chair” is a chair found on WWII submarines known to be “fashionably indestructible”.
People in submarines eventually need to sit down, and in 1944 aluminum company ALCOA collaborated with the U.S. Navy on the purpose-built 1006 Chair, also known as the Navy Chair or Submarine Chair. The design brief had at least one interesting bulletpoint: The chair had to be “torpedo-proof.”
The resultant super-strong chair is still in production today, manufactured by aluminum chair company Emeco.
Emeco even teamed up with Coca-Cola to make the chairs from recycled plastic.
